A VOW FOR THE MIZBE'ACH
Question: Nesachim are entirely for the Mizbe'ach!
Answer: They are poured through the Shitim. (The Mizbe'ach does not consume them.)
Question: Minchas Nesachim is entirely consumed by the Mizbe'ach!
Answer: Some Menachos are (mostly) eaten by Kohanim. Presumably the one who vowed intended for something that is always Kalil.
A VOW TO BRING METAL
(Mishnah): If one said 'Alai Zahav', he must bring at least a gold Dinar.
Question: Perhaps he meant Naska (an ingot; Tosfos - it is a fixed amount less than a Dinar)!
Answer (R. Elazar): He said 'coins'.
Question: Perhaps he meant Perutos!
Answer (Rav Papa): People do not make gold Perutos.
(Mishnah): If one said 'Alai Kesef', he must bring at least a Dinar.
Question: Perhaps he meant Naska!
Answer (R. Elazar): He said 'coins'.
Question: Perhaps he meant Perutos!
Answer (Rav Sheshes): The Mishnah discusses a place where silver Perutos are not used.
(Mishnah): If one said 'Alai Nechoshes', he must bring copper worth a silver Ma'ah.
(Beraisa - R. Eliezer ben Yakov): He must bring at least a small fork of copper.
Question: What use is there for this in the Mikdash?
Answer (Abaye): It is used to cut off burnt ends of wicks and to clean the ashes out of the lamps of the Menorah.
Version #1 (Beraisa - Others): If one said 'Alai Barzel', he must bring iron (at least) enough for Kalyah Orev (to prevent ravens from resting on the Heichal; Rashi - these are spikes, or an iron plate with a sharp edge pointing up; Aruch - it is a scarecrow.)
Question: How big must this be?
Answer (Rav Yosef): It must be one Amah by one Amah.
Version #2: If one said 'Alai Barzel', he must bring one Amah by one Amah.
Question: What use is there for this in the Mikdash?
Answer (Rav Yosef): It is enough for Kalyah Orev.
VOLUNTARY NESACHIM
(Mishnah): If one said 'Alai Yayin', he must bring three Lugim of wine;
If he said 'Alai Shemen', he must bring one Log of oil;
Rebbi says, he must bring three Lugim.
If he knows that he vowed to bring a certain amount but does not remember how much, he brings the largest amount that the Tzibur ever brings in one day.
(Gemara - Beraisa): "Ezrach" is extra, to permit a Nedavah of wine. Three Lugim must be brought. (We never find less than this.)
Question: What is the source to allow bringing more?
Answer: "Yihyeh" permits this.
Suggestion: Perhaps one may bring less!
Rejection: "Kachah" (is Me'akev).
(Mishnah): If he said 'Alai Shemen', he must bring one Log of oil; Rebbi says, three Lugim.
Question: What do they argue about?
Answer (Rabanan): Chachamim hold Dun Minah u'Minah (when a matter is learned from another matter, we learn everything from the source):
We learn Nedavah of oil from Menachos. The smallest amount of oil in a Minchah is one Log;
Rebbi holds, Dun Minah v'Uki b'Asra (we only learn one law from the source, other laws are according to the law of the matter being learned);
We learn from Menachos that a Nedavah can be brought, but we learn the Shi'ur from Nesachim. The minimum we ever find is three Lugim (of wine).
Rejection (Rav Papa): Both of them hold Dun Minah u'Minah. If they learned from Menachos, Rebbi would agree that the Shi'ur is one Log.
Answer #2 (Rav Papa): Rebbi learns from "Ezrach" (i.e. Nesachim of wine). Three Lugim must be brought.
Rejection (Rav Huna brei d'Rav Noson): That is wrong!
(Beraisa): "Korban" teaches that Nedavah of wine may be brought. The Shi'ur is three Lugim.
Rav Huna: This is like Rebbi, who holds that the Shi'ur is three Lugim. This shows that he learns from "Korban"!
Admission (Rav Papa): Indeed, the Beraisa refutes me.
UNSPECIFIED VOWS
(Mishnah): If one said 'Alai Olah', he must bring a lamb (or better);
R. Elazar ben Azaryah says, he brings a Tor or Ben Yonah (or better).
If he vowed to bring Bakar (cattle, for an Olah) but does not remember which, he brings a bull and calf;
If he vowed to bring a Behemah but does not remember which, he brings a bull and calf, ram and (adult) goat, kid (yearling goat) and lamb.
If he does not remember whether he specified an animal or bird, he brings all of these and a Tor or Ben Yonah.
If he vowed to bring Todah or Shelamim, he must bring a lamb (or a bigger animal);
If he vowed to bring a specific kind of Bakar but does not remember which, he brings a male calf and a female calf, and a bull and cow;
If he vowed a specific animal but does not remember which, he brings a male and female of each of the following - cow and calf, (adult) sheep and goat, kid and lamb.
If he vowed to bring a bull, he must spend (at least) a Maneh (25 Sela'im) for it and its Nesachim;
If he vowed to bring a calf, ram or lamb, he must spend (respectively) at least five, two or one Sela('im) for it and its Nesachim;
If he vowed to bring a bull (or calf, ram or lamb) for 25 (or five or two or one) Sela('im), he must spend this amount for the animal alone, without its Nesachim;
If he vowed to bring a bull for a Maneh and he brought two bulls for a Maneh, he was not Yotzei;
Even if each is worth almost a Maneh, he was not Yotzei.
If he vowed to bring a black animal and brought a white one (or vice-versa), or to bring a large animal and brought a small one, he was not Yotzei;
If he vowed to bring a small animal and brought a large one, he was Yotzei;
Rebbi says, he was not Yotzei.
(Gemara): The first Tana and R. Elazar ben Azaryah do not argue. R. Elazar gives the law in his locale (Rambam - there, people call Olas ha'Of (simply) Olah; Rashi - there, birds cost more than lambs), and the first Tana teaches for his locale. (Olah refers only to Behemos, or lambs cost more than birds.)
(Beraisa): If one vowed to bring an Olah for a Sela to the Mizbe'ach, he should bring a lamb, for no other animal can be offered for a Sela.
If he specified what he will bring for a Sela, but he does not remember what, he brings everything that can be offered for a Sela (also Soles, Levonah...)
A LARGE ANIMAL IN PLACE OF A SMALL ONE
(Mishnah): If he vowed to bring a specific kind of Bakar but does not remember which, he brings a bull and a male calf.
Question: It should suffice to bring a bull, even if he vowed to bring a calf!
Answer: Our Mishnah is Rebbi, who says that if he vowed to bring a small animal and brought a large one, he was not Yotzei.
Question (Mishnah): If he vowed to bring a bull for a Maneh and he brought two bulls for a Maneh, he was not Yotzei;
Even if each is worth almost a Maneh, he was not Yotzei.
If he vowed to bring a black animal and brought a white one (or vice-versa), to bring a large animal and brought a small one, he was not Yotzei;
If he vowed to bring a small animal and brought a large one, he was Yotzei;
Rebbi says, he was not Yotzei.
Summation of question: Will you say that the Reisha and Seifa are like Rebbi, and the middle is Rabanan?!
Answer: Indeed, the Reisha and Seifa are Rebbi, and the middle is Rabanan.
The Mishnah teaches that (not all agree to the Reisha); Rebbi and Chachamim argue about this.
(Mishnah): There were six boxes for Nedavah (money to buy Kitz ha'Mizbe'ach, Olos Nedavah of the Tzibur for when the Mizbe'ach is idle).
(Mishnah) Question: Why were there six?
Answer #1 (Chizkiyah): They correspond to the six Batei Avos (Rashi - subdivisions of each Mishmar of Kohanim), so there will be Shalom between them. (The money is divided equally, so each Beis Av will offer the same amount; R. Gershom - each Beis Av offers whatever is given on its day.)
Answer #2 (R. Yochanan): Because many coins were given for Nedavah, there were six boxes, lest the coins rot.
Answer #3 (Ze'iri): There was one box for each kind of animal (that one may vow to bring for an Olah, i.e. males) - bull, calf, ram, lamb, goat and kid;
This is like Rebbi, who says that if one brought a large animal in place of a small one, he was not Yotzei.
Answer #4 (Bar Pada): The boxes were for (redemption money of Korbanos sent to graze, e.g. if a replacement was offered in place of a lost Korban, e.g.) bulls and goats (of Chatas Tzibur), rams and lambs (of Ashamos), Mosaros (if one was Makdish money for a Korban and did not need all of it, the extra is Mosar) and Kalbonos (small additions to the half-Shekel that everyone must give to Hekdesh each year).
